SHAPEAGF (09/28/96)
To run SHAPEAGF, open a DOS window, and type SHAPEAGF on the command line.
SHAPEAGF converts a ArcView shape file into an AGF file for use with
Atlas GIS. It can also be used to display information about the
shapefile or the list of current projections.
This form of the command displays information about the shape file. It
will display the number of features, the type of feature, the boundaries
of the file, and the items on the file.
SHAPEAGF [shape_file] {output_file}
where:
[shape_file] The name of the shape file to use display information
about. You must have SHP, SHX and DBF files to list. Do not
include the suffix.
{output_file} An optional output file to send the information about
the shape file to. If not specified the output is displayed on
the screen.
This form of the command displays a list of all the current projections.
SHAPEAGF [COORDSYS] {output_file}
where:
[COORDSYS] Indicates that you want to see the list of
projections (COORDinate SYStems).
{output_file} An optional output file to send the list of projections
to. If not specified the output is displayed on the screen.
This form of the command converts a shape_file an AGF file.
SHAPEAGF [shape_file] [afg_file] [projection] [layer_name]
[id_item] {name1_item} {name2_item}
where:
[shape_file] The name of the shape file to use for the conversion.
You must have SHP, SHX and DBF files to do the conversion. Do
not include the suffix.
[agf_file] The name of the ATLAS AGF file to create. An AGF
and AIF file will be created. Do not include the suffix.
[projection] What projection or coordinate system the shape file
currently is in. There are numerous choices but a list can
be obtained by using the COORDSYS option.
[layer_name] The name of the layer that will be created on the
AGF file. This is limited to sixteen characters and must not have
any blanks. Please note that this parameter is case sensitive.
[id_item] The name of the item from the shape file that will be
used as the _ID field on the AGF file.
{name1_item} The name of the item from the shape file that will
be used as the _NAME field on the AGF file. This parameter is
optional.
{name2_item} The name of the item from the shape file that will
be used as the _NAME2 field on the AGF file. This parameter is
optional.
Notes:
To run this command you must have a COORDSYS file (from Atlas GIS) either
in your current directory, the directory that the program is run from or
the DATUM subdirectory under the ARCEXE directory (PC ARC/INFO users).
The COORDSYS file lists all the available projections supported by ATLAS
with the necessary parameters and data. The projection parameter on the
shapeagf command line tells what projection the data already is in. It
does not do a projection during conversion. You must know the projection
of the shape file data or you will have to specify USER, USER_2, USER_4
or USER_6 projections. Labels for each polyline are calculated by finding
the longest segment of the first line of the polyline and using the
midpoint of that segment. The angle of that segment is used for the angle
for the label.
Labels for each region are calculated by using the centroid of the first
polygon of a region. The angle of the label is zero. SHAPEAGF will skip
any shape feature that has more than 4090 vertices. There will be a
message displayed on the screen, and the conversion process will
continue. Before you open the resulting AGF file in Atlas, please run
the GEOFIX program found in the /agisw subdirectory on the AGF file.
Once you open the AGF file in Atlas, the index files will be rebuilt,
and the AGF file can then be used normally.

This shape file has 51 polygon shape records. The bounding box of
the shape file is displayed (-187.193, 18.925, -66.9525, 71.3425)
with a list of the items (STATES_ID, STATE, STATE_NAME,
POP_1980, POP_1990).
List some of the projections or coordinate systems that are
available. They are listed in alphabetical order.

Convert the shape file STATES to the AGF file USA. The projection

STATES_ID as the _ID field and STATE_NAME as the _NAME field.
